The work studies the results of the heat exchange process simulation through the bond of various types, the measurement of heat transfer resistance of the enclosure structure of operated buildings in Moscow, Stary Oskol and Belgorod. In addition, it studies the measurement results of the heat transfer resistance of enclosure structures under laboratory conditions to compare their actual burning characteristics and design values. The authors verified the cause of the mismatch between the actual

It is made clear that it is a structural design that exercises the main influence upon the actual heat transfer resistance of enclosure structures in relation to the design value, not the materials employed. It is found that the enclosure structures that have a heat insulation layer, set under construction, have the actual heat transfer resistance that is lower than the design value. The enclosure structures, made as a brick or block work and assembled under plant conditions, correspond to the stated properties by their heat-shield performance.
